Abstract
The utility model relates to the tractor installation technology field, and provides a gearbox and rear axle running-in testing stand. The testing stand is mainly composed of three parts, i.e. a driving device, a positioning connection device, and a lubricating oil circulating system. A gearbox and a rear axle which are fixed on the positioning connection device are correspondingly connected with a transmission shaft of the driving device, and the positioning connection device is connected with a support of the driving device to form a fixed integral body. The gearbox and the rear axle which are fixed on positioning connection device are connected with an oil feeding path of the lubricating oil circulating system. The positioning connection device is composed of a positioning dolly (6) on a guide rail (1) and a connection fixing device (8). The gearbox and rear axle running-in testing stand improves a conventional gearbox and rear axle running-in testing stand, and increases the positioning precision, reduces the labor intensity and the work noise, enhances the operation security and the convenience of maintenance, and improves the performance and the quality of a product finished by the test.
Description
Technical field
